, OIL-BURNER.

Specification of Letters Patent.

Application filed June 9, 1913.

Patented Mar. 3, 1914.

Serial No. 772,667.

To all whom it may concern:

Be it known that I, JOHN W. MA'ILOCK, a

citizen of the United States, residing at St-eelville, in the county of Crawford and State of Missouri, have invented certain new and useful Improvements in Oil-Burners, of which the following is a specification, reference being had therein to the accompanying drawing.-

This invention relates to oil burners, and the principal object of the invention is to provide an improved burner of the type in which the oil is vaporized and then caused to pass out through an opening where it may be ignited and not only used for heating purposes, but also to heat the oil in the generating pipe.

Figure 1 is a perspective View of a two-- burner heater constructed in accordance with this invention. Fig. 2 is a longitudinal sectional view through the heater. Fig. 3 is a top plan view of'the heater with the cover plate removed ,and the burner pipes re moved. Fig. 4 is a transverse section along.

the line 4- Fig. 1. Fig. 5 is an enlarged view of the coupling between the supply pipe and burner pipe. Fig. 6 is a perspective view of the deflector plate. Fig. 7 is a fragmentary sectional View through the end portion of one of the burner pipes. Fig. 8 a perspective view of a modified form of heater in which a single burner is used. Fig. 9 is a perspective view of the body portion of the burner shown in Fig. 8, a portion of the wall bein -broken away.

In the form s own in Fig. 1 the housing 10 is provided with an end portion 11 posit-ioned in the elevated plane and connected with the main portion of the body portion by a sloping neck 12. This end portion 11 is provided with an end wall 13 in the lower portion of which there is provided an opening 14 which permits the air to pass into the body portion and thus cause the necessary draft.

A cover 15 is carried by the body portion and is provided with a pair of circular openings 1(3 and with a pair of rectangular openings 17 provided with end extensions 18. Side flanges 19 are carried by the cover.

A pair of conical couplings 20 are carried by the body portion and are positioned as shown in Fig. 2 with their threaded necks 21 extending through the openings 16. These couplings 20 are connected with the curved pipes 22 by means of the collars 23, so that oil can flow from the coupling into the pipes and out through the openings 24; formed in the pipes. Plugs 25 are threaded into the ends of the pipes to close the ends, thus causing the oil to flow out through the openings 24. An elliptical deflector 26 is secured to each ofthc pipes 22 and is positioned above the o enings in the pipes so that the flame will 0 spread and this causes it to more thoroughly heat the upper portion of the pipe and thus heat the oil passing through the pipe.

It should be noted that the velocity of the vaporized oil passing through the pipe 22 is increased, due to the fact that the coupling 20 is conical. It is necessary that the stream of vaporized oil assing through opening 2% have considerable velocity, since this oil needs to be broken up so that it can mix with the air in the housing, thus causing a good flame to be produced. Pipes 27 and 28 lead from couplings 20 and have their outer end portions passing through the end wall 13 and connected with a double-ended valve housing 2!), which carries the valves 30 and 31 and is provided with a threaded-extension 32 by means of which a supply pipe can be connected with the valve housing.

In the operation of this form of burner, the housing is put in place and the supply pipe is connected with an extension 32. The valves 30 and 31 can then be opened and the oil will flow through the pipes 27 and 28 to the couplings 20 and into the pipes 22. As soon as a portion of the oil flows through the openings 24 it may be ignited and it will heat the oil in the upper portion of the pipe, thus causing it to vaporize and pass out through the opening. If it is desired to use only one burner one of the valves 30 and 31 may be shut oil and the supply of oil to one of the pipes22 will then be cut ofi. By this arrangement the two 30 air to near the same temperature as the oil burners may be used until the store is well heated and then one of them cut off, thus saving one-half of the oil.

In the form shown in Figs. 8 and 9 there is illustrated a similar heater using a single burner. This form comprises the housing 33 having a cover 34 which is provided with openings and 36 similar to the openings 16 and 17. This housing is provided with an opening 37 which takes the place of the opening 14 and carries a single conical coupling 38 which is similar to the couplings 20. The valve 39 is connected with the coupling by means of the short length of pipe -10 and a curved burner pipe 41 similar to the pipe 22 is connected with the threaded neck 12 of the coupling that passes out through the opening 35 and back through the opening 36. This pipe is provided with an outlet opening a3 positioned beneath the deflector plate 44 so that the flame will be spread. The operation of this burner is similar to that in the form shown in Fig. 1, and, therefore, a description of the operation is not necessary.

The box is so constructed that the air is heated as it passes through the air passages and the air passages act as a superheater, thereby giving more heat and eliminating the noise to a great extent by heating the before the mixture takes place.

What is claimed is:

1. A burner of the character described comprising a housing provided with an air inlet opening, a cover for said housing provided with a plurality of openings, a conical coupling in said housing positioned beneath one of the openings in said cover, a burner.

burner pipe, and a fuel supply pipe connected with said coupling.

2. A burner of the character described, comprising a housing having one end portion positioned in a higher plane than the major portion of the housing and connected with the major portion by an inclined neck, a cover for said housing provided with a plurality of openings, a conical coupling in the major portion of said housing positioned beneath one of the openings formed in said cover, a burner pipe con nected with said coupling and extending through another opening in said cover and carried over the opening abovethe coupling in the cover and bent downwardly and carried through the last-mentioned opening into the body port-ion and bentbeneath the upper portion and provided with an outlet opening, a deflector plate carried by the upper port-ion and positioned above the outlet opening formed in said burner pipe, and a supply pipe entering said body portion through the upper end portion and extending in said inclined neck and having its inner end portion connected with said coupling.

3. In a burner of the character described, a housing, a cover for said housing provided with a plurality of openings, a conical coupling in said housing, a burner pipe connected with said coupling and carried through one of said openings formed in the cover of said housing and having its outer end portion carried over a second opening formed in said cover and bent back through the last-mentioned opening beneath the upper portion and provided with an outlet opening, and a valve controlled supply pipe JOHN W.
